[0020] A method of using a valve body cleaning and grinding device, characterized in that, using the aforementioned valve body cleaning and grinding device, the method includes the following steps:

[0021] S1: In the initial state, place the valve body to be polished into the clamping assembly and fix it. Start the motor, and the motor will drive the valve body to rotate through the clamping assembly.

[0022] S2: During the rotation of the valve body, the brush in the first grinding assembly maintains sliding contact with the side wall of the main pipe, and the grinding work of the side wall of the main pipe is completed under the grinding action of the brush.

[0023] S3: The motor rotation drives the lever to rotate, which in turn drives the slider to slide along the first guide groove. With the cooperation of the telescopic cylinder and the telescopic rod, the slider drives the fixed rod to move along the second guide groove. Under the action of the second guide groove, the fixed rod drives the brush bucket to slide along the axial direction of the side tube, thereby realizing the sliding grinding work of the side tube. At the same time, with the cooperation of the rack in the second guide groove, the movement of the fixed rod drives the drive gear to rotate. The rotation of the drive gear drives the second bevel gear to rotate through the first bevel gear. The rotation of the second bevel gear drives the brush bucket to rotate around the axial direction of the side tube, thereby realizing the rotational grinding work of the side tube.

[0024] S4: When the lever rotates to the separation structure and contacts the separation structure, the lever separates from the slider under the action of the separation structure. Under the action of the return spring, the slider drives the fixed rod to move in the opposite direction along the second guide groove. The movement of the fixed rod drives the brush bucket to move, and finally completes the reset work of the fixed rod and the brush bucket.

[0025] S5: During the rotation of the valve body, the end brush in the third grinding assembly maintains sliding contact with the end of the main pipe, and the grinding work at both ends of the main pipe is completed under the grinding action of the end brush.

[0026] S6: After the grinding work is completed, stop the motor and remove the valve body from the clamping assembly.

[0027] As described above, the valve body cleaning and grinding equipment and its method of use of the present invention have the following beneficial effects:

[0028] 1. In this invention, a clamping assembly is provided on the base plate. The clamping assembly is used to fix the valve body and drive the valve body to rotate. The base plate is also provided with a first grinding assembly, a second grinding assembly, and a third grinding assembly. The first grinding assembly is located on one side of the valve body and is used to grind the side wall of the valve body main pipe. The second grinding assembly is located above the valve body and is used to grind the side pipe of the valve body. The third grinding assembly is located at both ends of the valve body and is used to grind the ends of the valve body main pipe. In use, the clamping assembly drives the valve body to rotate, and the first, second, and third grinding assemblies simultaneously grind the side wall of the valve body main pipe, the side pipe, and both ends of the main pipe, respectively. The grinding position is more comprehensive, the grinding effect is better, and the grinding efficiency is high.

[0029] 2. The clamping device of the present invention includes symmetrically arranged electric grippers, one of which is connected to a motor, and the other is coaxially connected to a gripper slide rod. The gripper slide rod passes through the gripper slider, and the gripper slider and the gripper slide rod are slidably connected. When fixing the valve body, the electric gripper passes through the cavity of the valve body's main pipe. The electric gripper can be opened or retracted to adapt to valve bodies with different main pipe diameters. Furthermore, with the cooperation of the gripper slide rod and the gripper slider, the distance between the two electric grippers is adjustable to adapt to valve bodies with different main pipe lengths, effectively improving the adaptability of the device.

[0030] 3. In this invention, the first grinding component includes symmetrically arranged first support columns. A brush slide rod is slidably connected to the upper end of the first support column. A brush is fixedly connected to one end of the brush slide rod that is close to the other. The brush slides in contact with the side wall of the main valve body. When the valve body rotates, the brush slides relative to the side wall of the main valve body, thereby completing the grinding of the side wall of the main valve body. When the side tube of the valve body contacts the brush, the brush slide rod slides relative to the first support column, and the two brushes move away from each other. The side tube slides between the two brushes without affecting the rotation of the valve body. Furthermore, a brush spring is sleeved on and slidably connected to the brush slide rod. After the side tube slides between the two brushes, the two brushes automatically reset under the action of the brush spring, effectively ensuring the overall grinding effect of the side wall of the main valve body.

[0031] 4. The third grinding component in this invention includes a guide plate with a first guide groove and a second guide groove. A slider is inserted and slidably connected in the first guide groove. A lever is sleeved and slidably connected to the end of a motor shaft. The motor drives the lever to rotate. The other end of the lever is in sliding contact with the slider. One end of the slider passes through the first guide groove and is fixedly connected to a telescopic cylinder. A telescopic rod is slidably connected inside the telescopic cylinder. A fixed rod passes through the second guide groove. One end of the fixed rod passes through the second guide groove and is fixedly connected to the upper end of the telescopic rod. The other end of the fixed rod passes through the second guide groove and is fixedly connected to a fixed head. A second bevel gear is sleeved and rotatably connected to the fixed head. A brush bucket for grinding the valve body is coaxially fixedly connected to the second bevel gear. The brush bucket is sleeved on the side tube of the valve body and is in sliding contact with the outer wall of the side tube. A drive gear is sleeved and rotatably connected to the fixed rod. A rack is provided on the inner wall of the second guide groove. The drive gear is positioned... The telescopic rod is fitted with a tension spring within the second guide groove and meshes with the rack. One end of the tension spring is connected to the telescopic cylinder, and the other end is connected to the fixed rod. A first bevel gear is coaxially fitted on the fixed rod. The first bevel gear is fixedly connected to the drive gear through several connecting rods, and the first bevel gear meshes with the second bevel gear. In use, the motor drives the lever to rotate, which drives the slider to slide along the first guide groove. The slider's movement drives the fixed rod to slide along the second guide groove, thereby causing the brush bucket to slide axially along the side tube, achieving the sliding grinding of the side tube. Simultaneously, under the action of the rack, the drive gear rotates, driving the first bevel gear to rotate. The rotation of the first bevel gear, through the second bevel gear, drives the brush bucket to rotate axially around the side tube, achieving the rotating grinding of the side tube. The simultaneous sliding grinding and rotating grinding are more conducive to improving the grinding effect of the side tube.

[0032] 5. In this invention, a return spring for driving the slider to reset is connected to the guide plate, and a separation structure is fixedly connected to the guide plate. When the lever contacts the slider, the separation structure separates the lever from the slider. Under the action of the return spring, the slider, the fixed rod, and the brush bucket automatically reset, without affecting the continued rotation of the valve body, so that the grinding work of the valve body can be carried out smoothly and is convenient to use.

[0045] like Figure 2-3 As shown, the present invention proposes a valve body cleaning and polishing device, including a base plate 9, a clamping assembly rotatably connected to the base plate 9, a motor 10 connected to the clamping assembly, and the clamping assembly is used to clamp and fix the valve body 28 and drive the valve body 28 to rotate.

[0046] The first grinding assembly is located on one side of the valve body 28. The first grinding assembly includes symmetrically arranged first support columns 4. The lower end of the first support column 4 is fixedly connected to the base plate 9. The upper end of the first support column 4 is slidably connected to a brush slide rod 6. A brush 8 is fixedly connected to one end of the brush slide rod 6 that is close to each other. The brush 8 slides in contact with the side wall of the valve body 28.

[0047] The second grinding assembly includes a guide plate 11, the lower end of which is fixedly connected to the base plate 9. A first guide groove 17 is formed on the guide plate 11, and a second guide groove 21 is formed around the first guide groove 17. A fixing rod 20 passes through the second guide groove 21, and a drive gear 22 is sleeved on and rotatably connected to the fixing rod 20. A rack is provided on the inner wall of the second guide groove 21, and the drive gear 22 is located within the second guide groove 21 and meshes with the rack. One end of the fixing rod 20 extends out of the second guide groove. A fixing head 271 is fixedly connected to the rear of the 21. A second bevel gear 26 is sleeved on and rotatably connected to the fixing head 271. A brush bucket 27 for polishing the side tube 280 is coaxially fixedly connected to the second bevel gear 26. The brush bucket 27 is sleeved on the side tube 280 and slides in contact with the outer wall of the side tube 280. A first bevel gear 25 is coaxially sleeved on the fixing rod 20. The first bevel gear 25 is coaxially fixedly connected to the drive gear 22 through several connecting rods 24. The first bevel gear 25 meshes with the second bevel gear 26. The system is as follows: A slider 15 is inserted and slidably connected within the first guide groove 17. One end of the slider 15 extends out of the first guide groove 17 and is fixedly connected to a telescopic cylinder 16. A telescopic rod 19 is slidably connected within the telescopic cylinder 16. The other end of a fixed rod 20 extends out of the second guide groove 21 and is fixedly connected to the upper end of the telescopic rod 19. A tension spring 18 is fitted onto the telescopic rod 19. One end of the tension spring 18 is connected to the telescopic cylinder 16, and the other end is connected to the fixed rod 20. A device for resetting the slider 15 is connected to the guide plate 11. The return spring 23 is connected to the slider 15 at the other end. The motor 10 shaft end is fitted with a lever 12. The motor 10 drives the lever 12 to rotate. The lever 12 slides along the axial direction of the motor 10 shaft. The other end of the lever 12 slides in contact with the slider 15. A separation structure is fixedly connected to the guide plate 11. The separation structure is located on one side of the first guide groove 17. The separation structure is used to separate the lever 12 from the slider 15. In the initial state, the slider 15 is located at the end of the first guide groove 17 away from the separation structure.

[0048] The third grinding component includes an end brush 29, which is fixedly connected to the base plate 9. The end brushes 29 are symmetrically arranged at both ends of the valve body 28, and slide in contact with the end of the main pipe 281.

[0049] The method for cleaning and polishing a valve body using the valve body cleaning and polishing equipment proposed in this invention includes the following steps:

[0050] S1: In the initial state, the valve body 28 to be polished is placed in the clamping assembly and fixed. The motor 10 is started and the motor 10 drives the valve body 28 to rotate through the clamping assembly.

[0051] S2: During the rotation of the valve body 28, the brush 8 in the first grinding assembly maintains sliding contact with the side wall of the main pipe 281, and the grinding work of the side wall of the main pipe 281 is completed under the grinding action of the brush 8.

[0052] S3: The rotation of motor 10 drives lever 12 to rotate, which in turn drives slider 15 to slide along the first guide groove 17. With the cooperation of telescopic cylinder 16 and telescopic rod 19, slider 15 drives fixed rod 20 to move along the second guide groove 21. Under the action of the second guide groove 21, fixed rod 20 drives brush bucket 27 to slide along the axial direction of side tube 280, thereby realizing the sliding grinding work of side tube 280. At the same time, with the cooperation of rack and pinion in the second guide groove 21, fixed rod 20 moves and drives drive gear 22 to rotate. Drive gear 22 rotates and drives second bevel gear 26 to rotate through first bevel gear 25. Second bevel gear 26 rotates and drives brush bucket 27 to rotate around the axial direction of side tube 280, thereby realizing the rotating grinding work of side tube 280.

[0053] S4: When the lever 12 rotates to the separation structure and contacts the separation structure, the lever 12 separates from the slider 15 under the action of the separation structure. Under the action of the return spring 23, the slider 15 drives the fixed rod 20 to move in the opposite direction along the second guide groove 21. The movement of the fixed rod 20 drives the brush bucket 27 to move, and finally completes the reset work of the fixed rod 20 and the brush bucket 27.

[0054] S5: During the rotation of the valve body 28, the end brush 29 in the third grinding assembly maintains sliding contact with the end of the main pipe 281. Under the grinding action of the end brush 29, the grinding work at both ends of the main pipe 281 is completed.

[0055] S6: After the grinding work is completed, stop the motor 10 and remove the valve body 28 from the clamping assembly.

[0056] In use, the motor 10 drives the valve body 28 to rotate through the clamping assembly. The first grinding assembly, the second grinding assembly and the third grinding assembly simultaneously grind the side wall of the valve body main pipe 281, the side pipe 280 and the two ends of the main pipe 281, respectively, so as to make the grinding position more comprehensive, the grinding effect better and the grinding efficiency higher.

[0057] like Figure 2-4As shown, in one embodiment of the valve body cleaning and polishing equipment of the present invention, the clamping assembly includes symmetrically arranged electric grippers 3. The two electric grippers 3 are located at both ends of the main pipe 281, one of which is fixedly sleeved on the shaft end of the motor 10, and the other electric gripper is coaxially inserted and fixedly connected to the gripper slide rod 2. The base plate 9 is fixedly connected to the gripper slider 1, and the gripper slide rod 2 cooperates with the gripper slider 1.

[0058] like Figure 4 As shown, in this embodiment, the electric gripper 3 includes a gripper body 300, which is cylindrical. The diameter of the gripper body 300 is smaller than the diameter of the main pipe 281. Three movable claws 301 are slidably connected to one end of the gripper body 300 along the radial direction. In use, the gripper body 300 passes through the main pipe 281, and the movable claws 301 are in close contact with the inner wall of the main pipe 281, so as to realize the connection and fixation of the electric gripper 3 and the valve body 28. Furthermore, the distance by which the movable claws 301 extend along the radial direction of the gripper body 300 is adjustable, thereby adapting to valve bodies 28 with different pipe diameters.

[0059] In this embodiment, two second support columns 31 are symmetrically arranged on the base plate 9. The two second support columns 31 are located at both ends of the main pipe 281 in the valve body 28. The motor 10 is fixed to the upper end of one of the second support columns 31. The gripper slider 1 is fixedly connected to the upper end of the other second support column 31. The gripper slide rod 2 passes through the gripper slider 1 and is slidably connected to the gripper slider 1. The relative sliding between the gripper slide rod 2 and the gripper slider 1 can be used to adjust the distance between the two electric grippers 3 to adapt to the main pipe 281 of different lengths.

[0060] In use, slide the gripper slide rod 2, which drives the connected electric gripper 3 to move, increasing the distance between the two electric grippers 3. Place the valve body 28 between the two electric grippers 3, and put the end of the main pipe 281 near the motor 10 onto the electric gripper 3 connected to the motor 10. Slide the gripper slide rod 2 in the opposite direction, and the gripper slide rod 2 drives the connected electric gripper 3 to pass into the end of the main pipe 281 near the gripper slide rod 2, thereby realizing the connection between the two electric grippers 3 and the valve body 28.

[0061] After the two electric grippers 3 are respectively inserted into both ends of the main pipe 281, the electric grippers 3 are activated. The moving claws 301 on the electric grippers 3 move away from each other and eventually contact the inner wall of the main pipe 281, thereby fixing the two electric grippers 3 to the valve body 28, which is conducive to adapting to main pipes 281 with different diameters.

[0062] With the cooperation of the electric gripper 3, the gripper slide bar 2, and the gripper slider 1, the clamping assembly can be adapted to valve bodies 28 of different lengths and pipe diameters, thereby effectively improving the adaptability of the clamping assembly and the device.

[0063] When the motor 10 is started, the motor 10 drives the valve body 28 to rotate through the electric gripper 3. At this time, the gripper slide rod 2 rotates inside the gripper slider 1. The cooperation between the gripper slide rod 2 and the gripper slider 1 also plays a supporting role, making the valve body 28 more stable when rotating, which is conducive to the smooth progress of the grinding work.

[0064] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment of the valve body cleaning and polishing equipment of the present invention, the first support column 4 is symmetrically arranged on one side of the valve body 28. The lower end of the first support column 4 is fixedly connected to the base plate 9. The upper end of the first support column 4 is fixedly connected to the brush slider 5. The brush slide rod 6 passes through the brush slider 5 and is slidably connected to the brush slider 5. The brush slide rod 6 is sleeved and slidably provided with a brush spring 7. One end of the brush spring 7 is connected to the brush slider 5, and the other end of the brush spring 7 is connected to the brush 8.

[0065] The height between the end of the brush 8 furthest from the brush slide bar 6 and the base plate 9 is higher than the height between the end of the brush 8 closest to the brush slide bar 6 and the base plate 9.

[0066] In this embodiment, the height between the ends of the two brushes 8 that are close to each other and the base plate 9 is higher than the height between the ends of the two brushes 8 that are far apart and the base plate 9. Initially, the ends of the two brushes 8 that are close to each other are in contact.

[0067] It should be noted that in this embodiment, the direction in which the motor 10 drives the valve body 28 to rotate is fixed. Under the drive of the motor 10, taking the valve body 28 rotating one revolution as an example, the side tube 280 of the valve body 28 first rotates to the bottom of the two brushes 8, passes between the two brushes 8, and then rotates to the top of the two brushes 8.

[0068] In use, in the initial state, the motor 10 drives the valve body 28 to rotate through the clamping assembly. During the rotation of the valve body 28, the outer wall of the main pipe 281 is always in sliding contact with the two brushes 8. Under the polishing action of the two brushes 8, the polishing work of the outer wall of the main pipe 281 is completed.

[0069] When the side tube 280 of the valve body 28 rotates to the bottom of the two brushes 8 and comes into contact with the two brushes 8, the side tube 280 continues to rotate. The brush slide rod 6 and the brush slider 5 slide relative to each other, compressing the brush spring 7. The two brushes 8 move away from each other and there is a gap between the two brushes 8. The side tube 280 slides through the gap between the two brushes 8, so as not to affect the rotation of the side tube 280. At this time, the ends of the two brushes 8 also have a certain polishing effect on the side tube 280.

[0070] After the valve body 28 slides upward from the gap between the two brushes 8, under the reset action of the brush spring 7, the two brushes 8 approach each other and eventually contact each other, completing the reset work of the brushes 8. This effectively avoids the situation where the side wall of the main pipe 281 is not completely polished due to the gap between the two brushes 8, which helps to ensure the overall polishing effect of the side wall of the main pipe 281.

[0071] like Figures 2-7 As shown, in one embodiment of the valve body cleaning and polishing equipment of the present invention, the guide plate 11 and the first polishing component are respectively located on both sides of the valve body 28. The guide plate 11 is located between the motor 10 and the valve body 28. The first guide groove 17 is arc-shaped, and the center of the circle where the first guide groove 17 is located is on the axis of the motor 10 shaft.

[0072] The guide plate 11 has a second guide groove 21 on the side of the first guide groove 17 away from the motor 10. The second guide groove 21 includes a first recess 210, a first protrusion 211, and a second recess 212. The first protrusion 211 is located between the first recess 210 and the second recess 212. A rack is fixedly connected to the first recess 210, the first protrusion 211, and the second recess 212.

[0073] A fixing rod 20 is inserted into the second guide groove 21. A drive gear 22 is sleeved on the fixing rod 20 and rotatably connected to it. The drive gear 22 is located in the second guide groove 21 and meshes with a rack. The end of the fixing rod 20 away from the motor 10 passes through the second guide groove 21 and is fixedly connected to a fixing head 271. A second bevel gear 26 is sleeved on the fixing head 271 and rotatably connected to it. A brush bucket 27 is coaxially fixedly connected to the second bevel gear 26. The brush bucket 27 is located above the side tube 280. The lower end of the brush bucket 27 is sleeved on the side tube 280. Brush bristles for polishing the side tube 280 are fixedly connected to the inner wall of the brush bucket 27.

[0074] Furthermore, the fixing rod 20 is also fitted with and rotatably connected to the first bevel gear 25, which is coaxially arranged with the drive gear 22. The first bevel gear 25 and the drive gear 22 are coaxially fixedly connected by three connecting rods 24.

[0075] A slider 15 is inserted and slidably connected inside the first guide groove 17. The cross-section of the slider 15 is an arc shape that matches the first guide groove 17. With the cooperation of the slider 15 and the first guide groove 17, the slider 15 can only slide along the first guide groove 17 and cannot rotate inside the first guide groove 17.

[0076] After the end of the slider 15 near the motor 10 passes through the first guide groove 17, it is fixedly connected to the telescopic cylinder 16. The telescopic cylinder 16 is located above the slider 15. A telescopic rod 19 is slidably arranged inside the telescopic cylinder 16. The lower end of the telescopic rod 19 passes through the telescopic cylinder 16, and the upper end of the telescopic rod 19 is fixedly connected to the fixed rod 20.

[0077] A tensioning spring 18 is also fitted and slidably mounted on the telescopic rod 19. One end of the tensioning spring 18 is connected to the upper end of the telescopic cylinder 16, and the other end of the tensioning spring 18 is connected to the fixed rod 20. The tensioning spring 18 has a pressing effect on the fixed rod 20, thereby ensuring that the drive gear 22 is always tightly meshed with the rack of the first recess 210, the first protrusion 211, and the second recess 212.

[0078] After the end of the slider 15 near the motor 10 passes through the first guide groove 17, it is also fixedly connected to the dial plate 14. The upper end of the dial rod 12 slides in contact with the dial plate 14. The rotation of the dial rod 12 drives the slider 15 to slide along the first guide groove 17 through the dial plate 14.

[0079] In the initial state, the slider 15 is located at the end of the first guide groove 17 near the first grinding component, and the fixed rod 20 and the drive gear 22 are located at the end of the second recess 212 near the first grinding component. At this time, the lower end of the brush bucket 27 is in sliding contact with the upper end of the side tube 280.

[0080] A return spring 23 is hinged to one end of the guide plate 11 near the first grinding assembly. The other end of the return spring 23 is connected to the slider 15. The return spring 23 is used to realize the reset of the slider 15.

[0081] A lever spring 30 is sleeved and slidably connected to the shaft end of the motor 10. The lever spring 30 is located between the motor 10 and the lever 12. One end of the lever spring 30 is connected to the shaft end of the motor 10, and the other end of the lever spring 30 is connected to the lever 12.

[0082] To separate the lever 12 from the dial plate 14, a separation structure is provided on the guide plate 11. The separation structure is located on the side of the first guide groove 17 away from the first grinding assembly. In this embodiment, the separation structure includes a guide block 13. One end of the guide block 13 is fixedly connected to the guide plate 11, and the other end of the guide block 13 is provided with an inclined portion 130. The inclined portion 130 slides in contact with the lever 12. The height between the end of the inclined portion 130 near the guide plate 11 and the base plate 9 is higher than the height between the end of the inclined portion 130 away from the guide plate 11 and the base plate 9.

[0083] In the initial state, the inclined part 130 is not in contact with the lever 12.

[0084] In use, in the initial state, the motor 10 drives the valve body 28 to rotate through the clamping assembly. At the same time, the motor 10 drives the lever 12 to rotate. The rotation of the lever 12 drives the slider 15 to slide along the first guide groove 17. The slider 15 drives the fixed rod 20 to move along the second guide groove 21 through the telescopic cylinder 16 and the telescopic rod 19.

[0085] Since both the slider 15 and the fixed rod 20 rotate around the shaft of the motor 10 under the action of the lever 12, the angular velocities of the slider 15 and the fixed rod 20 are the same, which ensures that the brush bucket 27 and the side tube 280 move synchronously.

[0086] The fixed rod 20 moves along the second guide groove 21 from the second recess 212 to the first recess 210. During the movement, the clamping spring 18 clamps the fixed rod 20. The drive gear 22 is always tightly meshed with the rack of the first recess 210, the first protrusion 211, and the second recess 212. Under the action of the rack, the drive gear 22 rotates around the fixed rod 20.

[0087] During the movement of the fixed rod 20 from the second recess 212 to the first recess 210, the radius of rotation of the fixed rod 20 around the shaft end of the motor 10 changes under the influence of the movement trajectory formed by the second recess 212, the first protrusion 211, and the first recess 210. This will affect the distance between the lower end of the brush bucket 27 and the side tube 280, thereby enabling the brush bucket 27 to slide and polish the side tube 280.

[0088] Specifically, when moving from the initial state, the radius of rotation first increases. When the drive gear 22 reaches the middle position of the second recess 212, the radius of rotation reaches a maximum value. During this process, the lower end of the brush bucket 27 and the upper end of the side tube 280 move away from each other.

[0089] As the drive gear 22 continues to move from the middle position of the second recess 212, the radius of rotation gradually decreases. When the drive gear 22 moves to the middle position of the first protrusion 211, the radius of rotation reaches a minimum extreme value, which is smaller than the radius of rotation in the initial state. During this process, the lower end of the brush barrel 27 and the upper end of the side tube 280 approach each other. Finally, the lower end of the brush barrel 27 is fitted onto the side tube 280. During the fitting process, the bristles inside the brush barrel 27 slide relative to the side wall of the side tube 280, thereby achieving the work of sliding and polishing the side wall of the side tube 280.

[0090] As the brush continues to move from the middle position of the first protrusion 211, the radius of rotation gradually increases, and the brush barrel 27 gradually slides out of the side tube 280. During the process of the brush barrel 27 sliding out, the bristles inside the brush barrel 27 slide relative to the side wall of the side tube 280, thereby realizing the sliding polishing of the side wall of the side tube 280.

[0091] During the movement of the fixed rod 20, the drive gear 22 rotates around the fixed rod 20 under the action of the rack. The rotation of the drive gear 22 drives the second bevel gear 26 to rotate through the first bevel gear 25. When the brush bucket 27 is fitted onto the side tube 280, the rotation of the second bevel gear 26 drives the brush bucket 27 to rotate around the axial direction of the side tube 280. The bristles of the brush bucket 27 slide relative to the side wall of the side tube 280, thereby realizing the work of rotating and polishing the side tube 280.

[0092] When the lever 12 rotates to the inclined portion 130 and comes into contact with it, as the lever 12 continues to rotate, relative sliding occurs between the lever 12 and the inclined portion 130 under the action of the inclined portion 130. The lever 12 moves toward the motor 10, and the contact area between the lever 12 and the dial plate 14 gradually decreases. Finally, the lever 12 separates from the dial plate 14, thereby releasing the connection between the lever 12 and the dial plate 14.

[0093] After the connection between lever 12 and lever 14 is released, under the action of return spring 23, slider 15 drives fixed rod 20 to move in the opposite direction along second guide groove 21, and finally completes the reset of fixed rod 20 and brush bucket 27.

[0094] As the motor 10 continues to rotate, the lever 12 continues to slide on the inclined portion 130 and eventually slips off the inclined portion 130. Under the action of the lever spring 30, the lever 12 returns to its original position.

[0095] The motor 10 drives the valve body 28 to continue rotating through the clamping assembly. The motor 10 drives the lever 12 to continue rotating. When the lever 12 re-contacts the lever plate 14, the side tube 280 continues to be polished.

[0096] like Figure 2 and Figure 3 As shown, in one embodiment of the valve body cleaning and polishing equipment of the present invention, end brush columns 290 are symmetrically connected on the base plate 9, and the two end brush columns 290 are respectively located at both ends of the valve body 28, and the end brush 29 is fixedly connected to the upper end of the end brush column 290.

[0097] Two end brushes 29 are located at both ends of the main pipe 281. The bristles on the two end brushes 29 slide in contact with both ends of the main pipe 281. During the rotation of the main pipe 281, the bristles on the end brushes 29 slide relative to the main pipe 281, thereby achieving the polishing work on both ends of the main pipe 281.

[0098] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
